Low testosterone is associated with insulin resistance

A study published recently in the European Journal of Endocrinology links to the previous post on erectile dysfunction as a predictor of death with cardiovascular disease. The authors mention the well-known fact that:

"Insulin resistance is associated with metabolic syndrome and type 2 diabetes, representing a risk factor for cardiovascular disease."

They set out to investigate a link between insulin resistance and low testosterone, even in the absence of overweight. What did their data show?

"In older men, lower total testosterone is associated with insulin resistance independently of measures of central obesity. This association is seen with testosterone levels in the low to normal range."

Do you see the connections between erectile dysfunction, cardiovascular disease, insulin resistance and low testosterone that are emerging here?
